Turbulent flow and splashing may result in carryover of flavor and may cause turbulent flow of beverage through outlet 148 of nozzle 100. As will be appreciated by one skilled in the art, the flow rate may be increased above 2 ounces per second if a diameter of an outlet 148 of nozzle 100 is also increased. Increasing a flow rate without increasing diameter of outlet 148 could result in base liquid backing up within receptacle 140, which may also result in turbulent flow and base liquid entering dry zone 149, which is undesirable.
  • a receptacle 140 of a beverage dispensing nozzle 100 is in fluid communication with diffuser assembly 150 and with flavoring inlets 124, as shown in FIG. 10.
  • Diffuser assembly 150 is configured to provide a laminar flow of base liquid into receptacle 140 along inner wall 141 of receptacle 140. Flavoring flows through flavoring inlets 124 of nozzle head 120 directly into receptacle 140. Flavoring flows through an open central portion of receptacle 140 along a longitudinal axis X of nozzle 100. Receptacle 140 directs the flow of base liquid and flavoring to outlet 148 so that base liquid and flavoring are dispensed through outlet 148 of nozzle in a laminar flow pattern.
  • peripheral openings 172 of second diffuser plate 170 may be arranged so as to direct the base liquid along inner wall 141 of receptacle 140.
  • an inner edge 173 of peripheral opening 172 is aligned with inner wall 141 of receptacle, as best shown in FIG. 10.
  • flow of base liquid makes a smooth transition from diffuser assembly 150 to receptacle 140.
  • Flow of base liquid may proceed along a line tangential to a curvature of inner wall 141 of receptacle 140. Flow of base liquid remains attached to inner wall 141 of receptacle 140.
  • inner edge 173 of peripheral opening 172 may be spaced inwardly from inner wall 141 and direct base liquid along inner wall 141. In such embodiments, inner edge 173 of peripheral opening 172 may be spaced from 0.1 mm to 5 mm from inner wall 141 at upper end 144 of receptacle 140.
  • a dry zone 149 may be created within receptacle 140, as shown in FIG. 10. Dry zone 149 may be a region surrounding outlets 134 of flavoring inlets 124 of nozzle head 120 within receptacle 140 in which no liquid is present at any time during operation of nozzle 100. If a base liquid contacts outlets 134 in receptacle 140, drops of flavoring remaining in flavoring inlet 124 may be drawn into receptacle 140, contaminating the beverage being dispensed with flavorings that may not have been selected to be dispensed. Thus, it is important to minimize or prevent splashing within receptacle 140 into dry zone 149.
  • Flavoring flows from flavoring outlet 134 on base 130 of nozzle head 120 through an interior of receptacle 140. Flavoring outlets 134 may be longitudinally aligned with outlet 148 of receptacle 140 so that the flavoring flows directly to outlet 148. Flavoring F intersects with base liquid B within receptacle 140 at intersection I located at outlet 148 or immediately adjacent to outlet 148, as shown for example in FIG. 10. The flow of flavoring interrupts the flow of the base liquid where the flavoring intersects the base liquid, which may result in splashing or turbulent flow. Thus, the flavoring intersects the base liquid at outlet 148 to minimize such effects within receptacle 140. [0065] Receptacle 140 of nozzle 100 is shown for example in FIGS. 11-13. Receptacle
  • Receptacle 140 directs base liquid and flavoring toward an outlet 148 of receptacle 140 to be dispensed from nozzle 100.
  • Base liquid and flavoring intersect within receptacle 140 at intersection I and exit outlet 148 together.
  • Receptacle 140 includes an open upper end 144 and a lower end 142 that is open at outlet 148.
  • Outlet 148 may be arranged centrally on receptacle 140, as best shown in FIGS. 12 and 13.
  • Receptacle 140 may taper from upper end 144 toward lower end 142, such that a diameter Di of upper end 144 is greater than a diameter D2 of lower end 142 at outlet 148, as best shown in FIG. 12.
  • D2 may be 0.200 inches to 0.800 inches, 0.300 inches to 0.700 inches, or 0.400 inches to 0.600 inches.
  • receptacle 140 may taper linearly so that receptacle 140 has a generally conical shape. However, in some embodiment, receptacle 140 may have a curvature, as shown in FIG. 11.
  • receptacle 140 may further include vanes 146, as shown for example in FIG. 12.
  • Vanes 146 may be disposed on an inner wall 141 of receptacle 140 and may extend generally perpendicularly from inner wall 141.
  • Vanes 146 may be arranged radially around outlet 148 of receptacle 140 and may extend from lower end 142 toward upper end 144 of receptacle 140.
  • Vanes 146 may be evenly spaced around outlet 148 and may be arranged at a fixed interval.
  • Vanes 146 may be arranged symmetrically when viewed from the top-down, as shown in FIG. 12.
  • each vane 146 may have the same shape and dimensions.
  • Vanes 146 define flow channels 147 for base liquid to flow within receptacle 140 toward outlet 148. Vanes 146 may help to prevent swirling of base liquid within receptacle 140, which may cause base liquid to exit through outlet 148 at an angle relative to a longitudinal axis X of nozzle 100. While diffuser assembly 150 is configured to evenly distribute base liquid around receptacle 140, there may be a somewhat greater flow of base liquid in one portion of receptacle 140, which may cause base liquid to swirl within receptacle 140 or cause streamlines of base liquid flowing along inner wall 141 to split or separate and rejoin chaotically in the absence of vanes 146, splitting of the streamlines may also result in splitting or deflection of the flow shape through outlet 148.
  • vanes 146 help to control the direction of flow of base liquid within receptacle 140, direct the flow of base liquid toward outlet 148, and help form a uniform and laminar flow from outlet 148.
  • receptacle 140 of nozzle 100 may have 4 to 20 vanes, 8 to 18 vanes, or 12 to 16 vanes. In some embodiments, receptacle 140 may include 14 vanes.
  • vanes resulted in the most uniform and laminar flow from outlet 148 with an outlet diameter D2 in a range of 0.500 inches to 0.600 inches and a flow rate of approximately 2.0 ounces per second and given the overall size of the nozzle as characterized by a diameter Di of approximately 1.900 inches.
  • a different number of vanes may be appropriate depending on the dimensions of the nozzle assembly (e.g., Di and D2), and the flow rate of the nozzle.
  • a nozzle having a relatively small outlet diameter D2 and a relatively small overall size Di and a greater base liquid flow would require fewer vanes, and a nozzle having a relatively large outlet diameter D2 and overall size Di, and a lower base liquid flow rate would require a larger number of vanes.
  • an outflow stabilizer 190 may be arranged within the outlet 148 of receptacle 140 in order to promote dispensing of beverage from nozzle 100 in a direction along a longitudinal axis X of nozzle 100, as best shown in FIG. 12. As base liquid flows along an inner wall 141 of receptacle 140, the flow of base liquid may cause base liquid to flow through outlet 148 at an angle relative to a longitudinal axis X of nozzle 100.
  • diffuser assembly 150 is configured to evenly distribute base liquid to receptacle 140, flow of base liquid may not be uniform through receptacle 140 at all times, and if the flow of base liquid is greater in one portion or side of receptacle 140, the flow of base liquid through outlet 148 may flow at a slight angle relative to a longitudinal axis of nozzle 100.
  • Outflow stabilizer 190 may help to prevent the base liquid that flows along the inner walls 141 of receptacle 140 from colliding at outlet 148, which may otherwise divert the flow of the base liquid and flavoring through outlet 148.
  • Outflow stabilizer 190 may have an X-shape or a cross-shape configuration and is arranged so as to divide outlet into multiple outflow regions 192. In some embodiments, outflow stabilizer 190 may have other shapes so as to divide outlet 148 into various numbers of outflow regions 192. The beverage flowing past outflow stabilizer 190 brings the beverage together into a uniform, aesthetically pleasing stream.
  • nozzle 100 may be operated by a control system.
  • control system may cause a selected base liquid, such as carbonated water, to flow through the nozzle, and control system may also cause a selected flavoring to flow through the nozzle.
  • control system may actuate one or more pumps for causing base liquid and flavoring to flow from a base liquid source or a flavoring source to the nozzle.
  • the base liquid and flavoring may combine “in flight” as the base liquid and flavoring flow from the nozzle to a beverage container. The base liquid and flavoring may mix and combine further within the beverage container.
  • the base liquid may continue to be dispensed for a brief period of time after the flavoring stops being dispensed.
  • the period of time may be 100 ms to 400 ms, and in some embodiments may be 200 ms. In this way, any flavoring that may remain within the receptacle 140 of nozzle 100 can be washed out by the base liquid.
  • receptacle 140 may further include a vent for equalizing a pressure within nozzle 100 and external air pressure.
  • beverage dispensing nozzle 100 may include a vent tube 180, as shown for example in FIG. 14.
  • Outlet 148 of beverage dispensing nozzle 100 may be sized so as to slightly restrict flow at outlet 148, which may help to provide a substantially cylindrical flow of base liquid through outlet 148 without ripples.
  • base liquid may back up at outlet 148 and may become trapped in receptacle 140 at the end of the dispensing operation. The backup of base liquid may result in carryover of flavor.
  • Vent tube 180 serves to equalize the internal air pressure within the nozzle and external air pressure, allowing the base liquid to fully drain and preventing base liquid from becoming trapped within receptacle 140 at the end of the dispensing operation. Vent tube 180 may also help to promote a smooth flow of liquid through outlet 148.
  • Vent tube 180 may include a hollow tubular member configured to place an interior of receptacle 140 in fluid communication with an area external to beverage dispensing nozzle 100. Vent tube 180 may be arranged parallel to a longitudinal axis X of nozzle 100 (and of receptacle 140). Vent tube 180 may also be offset from a center of receptacle 140 so that flavoring flowing through a central portion of nozzle 100 does not contact vent tube 180. Vent tube 180 includes an upper end 184 arranged within receptacle 140 and a lower end 182 outside of receptacle 140 and adjacent outlet 148 of receptacle 140 so that lower end 182 is open to the environment.
  • Vent tube 180 may include an opening 181 at upper end 184 and may include an open lower end 182. In this way, air may flow from an exterior of receptacle 140 to an interior of receptacle 140 (and of nozzle 100), or air may flow in the reverse direction from the interior to the exterior so as to equalize interior and exterior pressures. Opening 181 at upper end 184 may be arranged on a sidewall of vent tube 180 and thus may extend in a direction transverse to longitudinal axis X to prevent liquid from escaping nozzle 100 through vent tube 180.
  • receptacle 140 may alternatively or additionally include vent holes 188, as shown in FIG. 15.
  • Vent holes 188 may function similarly to vent tube 180 of FIG. 14, and may serve to equalize the internal air pressure within the nozzle and external air pressure. In this way, vent holes 188 may help to allow base liquid 300 to fully drain, preventing base liquid 300 from becoming trapped within receptacle 140 at the end of the dispensing operation.
  • or more vent holes 188 may be formed around a periphery of receptacle 140. Vent holes 188 may be laterally oriented, and thus may be oriented perpendicular to a longitudinal axis X of nozzle 100. Vent holes 188 may be located at upper end 144 of receptacle 140 and may be positioned such that the holes are not in a direct flow path of the base liquid flow from diffuser assembly 150 onto inner wall 141 of receptacle 140.
